Those are shots of the raw print, not casts.
There were a pair of small bumps on the backside, but they popped off with a quick flick of the knife. As it took me all of 30 seconds I didn't consider it "cleaning". So having these come from the printer like this left me pretty amazed and happy as it saves me a boatload of time compaired to previous models. They also cast up very nicely, didn't need any primer they came out of the molds perfectly smooth.
I'll toss some resin shots up soon.
The neck piece can be cut and moved up quite easily.
